Fluctuation of Bunch Length in Bursting Regime: Measurement and Simulation — •Patrik Schönfeldt1, Markus Schwarz1, Nicole Hiller2, and Anke-Susanne Müller1,2,3 — 1LAS, KIT, Karlsruhe — 2IPS, KIT, Karlsruhe — 3ANKA, KIT, Karlsruhe
This talk is based on bunch length measurements taken in low-alpha-operation at the ANKA synchrotron light source (KIT, Germany). Above the bursting threshold not only bursting of coherent synchrotron radiations occurs but also a continuous fluctuation of the bunch's length. In particular, it has been observed that the growth of bunch length with increasing current is not strictly monotonic. The measurements were carried out using concurrent multi turn (using a streak camera) as well as single shot (using electro-optical spectral decoding) methods. Furthermore, we compare information obtained on the fluctuation to simulations.
